- UBWINO WA SILICON CARBIDE YOKHUDZANA NDI CHIKONDI
Zogulitsa za Reaction Bonded Silicon Carbide (RBSC, kapena SiSiC) zimapereka kukana kuuma/kutupa kwambiri komanso kukhazikika kwa mankhwala m'malo ovuta. Silicon Carbide ndi chinthu chopangidwa chomwe chimagwira ntchito bwino kwambiri kuphatikiza:
lKukana mankhwala bwino kwambiri.
Mphamvu ya RBSC ndi yaikulu pafupifupi 50% kuposa ya ma carbide ambiri a silicon olumikizidwa ndi nitride. RBSC ndi ceramic yabwino kwambiri yotsutsa dzimbiri komanso antioxidation. Ikhoza kupangidwa kukhala mitundu yosiyanasiyana ya desulpurization nozzle (FGD).
lKukana bwino kuvala ndi kukana kukhudzidwa.
Ndi chinthu chapamwamba kwambiri paukadaulo waukulu wa ceramic womwe sungathe kusweka. RBSiC ili ndi kuuma kofanana ndi kwa diamondi. Yopangidwira kugwiritsidwa ntchito popanga mawonekedwe akuluakulu pomwe mitundu yotsutsa ya silicon carbide ikuwonetsa kuwonongeka kapena kuwonongeka chifukwa cha kukhudzidwa ndi tinthu tating'onoting'ono tating'onoting'ono. Yosagonjetsedwa ndi kugwedezeka mwachindunji kwa tinthu tating'onoting'ono komanso kugwedezeka ndi kutsetsereka kwa zinthu zolimba zomwe zili ndi slurry. Itha kupangidwa kukhala mitundu yosiyanasiyana, kuphatikiza mawonekedwe a cone ndi sleeve, komanso zidutswa zovuta kwambiri zopangidwa ndi zida zomwe zimagwiritsidwa ntchito pokonza zinthu zopangira.
lKukana kutentha kwambiri.
Zigawo za silicon carbide zolumikizidwa ndi reaction zimapereka kukana kwakukulu kwa kutentha koma mosiyana ndi zoumba zachikhalidwe, zimaphatikizanso kukhuthala kochepa ndi mphamvu yayikulu yamakina.
lMphamvu yayikulu (imapeza mphamvu kutentha).
Silicon carbide yolumikizidwa ndi reaction imasunga mphamvu zake zambiri zamakaniko kutentha kwambiri ndipo imakhala ndi mphamvu zochepa kwambiri, zomwe zimapangitsa kuti ikhale chisankho choyamba chogwiritsidwa ntchito ponyamula katundu pakati pa 1300ºC mpaka 1650ºC (2400ºC mpaka 3000ºF).

Kupanga Mphamvu, Kukumba Migodi, Mankhwala, Petrochemical, Kiln, Makampani opanga makina, Mineral & Metallurgy ndi zina zotero.
Komabe, mosiyana ndi zitsulo ndi zitsulo zake, palibe miyezo yokhazikika ya magwiridwe antchito a silicon carbide. Ndi mitundu yosiyanasiyana ya zinthu, kuchulukana, njira zopangira komanso chidziwitso cha kampani, zigawo za silicon carbide zimatha kusiyana kwambiri pakukhazikika, komanso mawonekedwe a makina ndi mankhwala. Kusankha kwanu kwa ogulitsa kumatsimikizira mulingo ndi mtundu wa zinthu zomwe mumalandira.
